Be Aitgknown that I', Devin GRAHAM, a citizen Toi `the United. States, residin at Bordulac', in 'the county of Fosterand tate of -North Dakota, have invented certain new andr usefullmprovements in Stackers Afor, f

Harvesters, of which Nthe' following is la specification,reference being hadv therein to the-accompanying drawing.v l'1 f The invention relates to an apparatus for the stackingv and maturing. ofcereal grains or the-like, and consists in the-parts andk combinations thereof herein set, forth and claimed, the same comprising a wheel sup# ported means for forming. anddepositing a stack of the unboundstraws and 4attached grain berries, adapted to travelwith a cutting apparatus having.' grain carrying and distributing.. means by 'which thek grain,V as it iscutyis delivered into thestack formen 13 f -Among the objects and advantages of the` invention-are the'saving of time and labor in Ycutting and-handling the'grain prepar' atoryl to threshing; thev better'drying Aand curing .of the grain iny loose form-.as distinguishedfromboundl form thesaving of the expense incident to the Ibinding system including cost of machinery andbreakage or failure infoperation of the same,y rwith consequent loss ofl valuable time inthe'limited harvesting season; repairs of binding ma-V chineryj; the cost of binding twine; the loss of-grain rattledV outrfrom the grain heads by Such machinery and in handling thev bundles after binding; the further` saving 1'. of labor and time vin gatlieringup widely scattered bundles or small shocks, and also of time' with respect to theoccupationo the land b v widely distributed harvested grain which Vdelaysthe preparationxof the land'for the next crop; and, in general, the substitution .forall ot these operations of machinery which is relatively simple and inexpensive,

,. requiring few and simple repairs,1and which is nevertheless-eiicient in operation,-in place .fof the more complicated and expensive 'Ina-y inmortancepchineryiheretofore.in general use. f In addition .to these rvconsiderations isthe material improvementin thegrain berriesin weight, grade and value, which is of they greatest T.Vith such objects in view, aswell as other adrantageswhichmay be incident tothe use of theimprovements, the-'invention fconsifstsl in vthe parts Vand combinationsthereoil hreinafterset .forth andclaimed,-W-ith the HARVESTERS.

former body'isV carried bya base frame',- and said `frameis carried by grondvwheelsgl", Sar-V ranged near ,thefrniddle' ofv the machine-so that the body is .verynearly balanced, withf' a 'slight p'reponderating 4weight vat` the front e clined front members 4 and a front cross bar 5, the whole being preferably' formed in one piece of angle iron. 6 is an arched frame lmember the lower part of which isV secured to the bars 3 at the front of the same, and 7 is a similar or somewhat higher arched member'attached to the side bars at their rear ends and at the stack depositing end ot' the machine. 8 is a cross bar secured to the members il near the lower end of the' varched member 6. 9, 9 indicate horizontal truss 'frames extending outwardly from the side bars, one at'each side-ol` the machine, attached by bolts l0 to the base frame at their front and rear ends, and also connected therewith at intermediate points by hori zontal frame members 1l. The wheels i are arranged within said truss frames 9 and are carried on an aXle l2 which extends across the machine under the base frame thereof andiis mounted in bearings 13., lll (Fig. Ll) which are attached to the under sides'oi the bars 3 and 9.1 l5k is'a'longitudinal frame member for the attachment oiLx the front ground wheel 2, bolted'to the frame members 8 and 5 It is provided with a vertical bearing ll'for the stem pivot l? of the caster wheel; 18 is a collar lined on theupper end of said pivot by a set screw 19 (F ig. 5). 2O is a draft attachment secured Vto the front end of the base frame.

The side walls of the stack former are indicated at 2l and are mounted at their rear ends by hinges 22 on the rear arch 7, so that they maybe moved outward and inward for the release of a formed stack andto return to normal position. The front wall .of the former is shown at 23 and lixedly attached to the front arch 6. The'rrear end oi' the former is closed 'for the forming ot the stack by an end gate Qlwhich is mounted near the top of the'rear arch 7 by a transverse pivot rod 25 (Fig. Ll).

The conlin'ing walls 2l and andsaid end gate may be suitably constructed of boards, sheet metal, lattice work, woven wire, or heavy canvaaj as may be preferred.` AVln the construction illustrated Vthe side walls are formed of boards (Figs-land 2), the front wall of a metal framework to which are attached vertical rods, forming a lattice work (Fig. 3), and the end-gate of a lattice work of wooden slats (Fig. 4l). That side wall over which-the' grainis to be delivered to the former may have an outwardly inclined top portionV 26 (Fig. to facilitate Vsuch operation.`= l" 1 Theside walls are swung outwardffor limiteddistance by links 27 arranged outside ofthe front wall`23 and 4pivotally connected at'QQ with brackets 30 which are bolted to boltedto the arch 6.

the inner sides of the front ends of the walls 2l (Fig. ll). l

The pivots 29 in the brackets 30 pass from theV inside tothe outside of the stack 4former through a slot 3l in the front wall.. This slot is formed by angle bars 32 `which are further controlled and vguided and held from distortion by the weight of the stackbyk frames 33 whichare bolted to the side walls at Ell and carry at their inner ends forward projectionswhich'work in the slot 3l. These projections lare'V preferably formed by rollers fitting in the slot, washers 3 7 which engage the inner"V and outer v'faces of Vthe angle bars andv bolts lfwhirh pass through said washers and rollers andthrouch the inner ends of the frames The lpivots 29lmay have'similarrollers 39 and washers 40. `The links 2? are' pivoted at ll to the upper and lower arms of a lever 42 and the upper arm oll `said lever is formed to be operated by handler the release' of the stack and for the returnv of the lside walls to their normal inward position.- 43 is a lined rack attached tofthe arch"by'whichtlre lever 42 is held ink its adjustediposition. Before the formationV of -a stack'fthelever 42 is so operated asto vThe side walls are draw the vforwardends `of the side wallsl i Vinivard until-they are nearer together than `afre'fthie rearfends, Vand tliefinterior of the stackV 'former liares rearwardly.' AWhen said 4forward ends` are released and the stack is depositedf'the side walls and parts 'of the sta ck former becoma'oranay be, furtherand further'a'way from the sides of the stack as the machine moves forward from the stack4 so as to deposit the stack inj'as perfect form as possible and without undue friction.

The rearfend gate 2li isnhe'ld closed and is released by armsfld pivoted at l5 on brackets 46 which arefboltedto the rear 'frame arch 7 (Fig. 8)."f-The outer ends oiC said' armsfare connectedb)r pivots l? Vwith the rear ends of rods'48. When the gate is'released to fswing outward and upward for the deposit of a formed stack said parts assume the positions' shown b v dotted lines in. Fig. 8. The rods 48 extend forward at thesideslot' the lformerl (Figs. l and 2), assingthioiigh guides 49 attached to frame members 50. 50. Upper side frame bars 5l are Vattachedto the 'arches 6 and 7. brace members-52, connect the bars 5l with lthe yarches '6 an'd-7 respectively, .and-

Inclined 56" indica-tesYbraces by tor the use the under sides `of the ,platforms or tables 87 are bumpers or stops 105 adapted to engage the frame bai' 86 to limit the rearward movement of the tables, and adapted to engage the bar 73 when-the tables are in their nor-mal forward position. The,top boards of said tables are attached to the frontand rear wheel-carrying cross pieces 1 06. The tables are 5preferably covered von top with galvanized iron which becomes ,very smooth in use so that the 'tables readily disengage from under the formed stack leaving it Vintact.
